  • the laundry treating apparatus of the related art is generally provided such that one tub and one drum are provided in one cabinet. That is, it is general that one laundry treating apparatus includes one laundry treating portion having a tub and a drum.
  • an auxiliary washing machine may be provided on a main washing machine, or vice versa. That is, two washing machines may be provided on or below one cabinet, whereby a user may perform separate washing and simultaneous washing through one washing machine.
  • This machine may be referred to as a twin washing machine or a twin laundry treating apparatus.
  • the auxiliary washing machine has no option but to be smaller than the general washing machine of the related art. Therefore, since a space of the auxiliary washing machine is relatively small, it is not easy to manufacture the auxiliary washing machine. This is because that various components provided in a large scaled washing machine are also required for the auxiliary washing machine of a small size. There is a difficulty in arranging and assembling the various components in a limited space.
  • the present invention is directed to a laundry treating apparatus that substantially obviates one or more problems due to limitations and disadvantages of the related art.
  • An object of the present invention is to provide a laundry treating apparatus that may be manufactured easily and used conveniently.
  • Another object of the present invention is to provide a laundry treating apparatus that may be manufactured easily by improving a structure of a top cover for covering upper portions of a tub and a drum.
  • Still another object of the present invention is to provide a laundry treating apparatus that may be manufactured easily by providing a detergent box and a detergent water supply pipe for supplying washing water to the detergent box in a top cover before the top cover covers upper portions of a tub and a drum.
  • Another object of the present invention is to provide a laundry treating apparatus that may be manufactured easily by forming a housing having front and rear sidewalls and left and right sidewalls to receive a tub and a drum therein, and has a simple configuration.
  • Another object of the present invention is to provide a laundry treating apparatus that may be manufactured by connecting the outside of a housing with inner components of the housing.
  • a laundry treating apparatus includes a housing; a tub provided inside the housing, for storing washing water therein; a drum rotatably provided inside the tub, for storing laundry therein; and a top cover provided above the housing to cover upper portions of the tub and the drum, wherein the housing includes front and rear and left and right sidewalls to define a space therein; and an extending portion formed to have a front and rear spacing and an up and down spacing from the top cover above the front sidewall so that an entrance space is formed from the front upper portion of the front sidewall to the inside of the housing.

  • the laundry treating apparatus may further include a detergent box mounted to a lower portion of at least one of a front left side or a front right side of the top cover.
  • the detergent box may be placed inside the housing in a manner such that the detergent box is mounted to the top cover, and then the top cover is mounted to the housing. Therefore, a structure or manufacturing process for mounting the detergent box in the housing may be omitted.
  • connection pipe is provided between the tub and the detergent box, and a connection portion where the connection pipe is connected with the detergent box is located at the rear of the extending portion. Therefore, a worker or assembler may gain access to the connection pipe through the extending portion from the outside of the housing. As a result, the worker or assembler may easily connect the connection pipe to the detergent box inside the housing through the extending portion.
  • connection pipe is first coupled to the tub.
  • the top cover is mounted to the housing.
  • connection between the opposite end of the connection pipe and the detergent box may be achieved through the extending portion.
  • connection pipe may be formed of a flexible material so as to stretch a certain distance. That is, the connection pipe may interconnect the detergent box and the tub in a stretched state. This means that the connection pipe is in the form of a straight pipe between the detergent box and the tub. Therefore, a detergent and washing water may be smoothly supplied to the tub from the detergent box.
  • connection pipe may be installed to interconnect the detergent box and the tub prior to mounting of the top cover to the housing.
  • the connection pipe may be in the stretched state.
  • the connection pipe is inevitably folded inside the housing. Due to the folding of the connection pipe, the detergent and washing water may not be smoothly supplied to the tub. Further, it may be required to use a longer connection pipe than necessary, and accordingly manufacturing costs may be increased. Therefore, it is very preferable to enable access to the inside of the housing through the extending portion from the outside of the housing in order to realize connection between the detergent box and the connection pipe.
  • connection pipe and the detergent box may be provided with a hook, and the remaining one of the connection pipe and the detergent box may be provided with a hooking portion to which the hook is hooked.
  • the connection pipe may be securely fixed to the detergent box without a risk of separation therefrom.

  • the laundry treating apparatus may further include a drawer panel coupled with a drawer body at the front of the front sidewall of the housing, and the drawer panel may be directly mounted to the drawer body. That is, a structure that is present between the drawer panel and the housing may be omitted.
  • an interval support rib extends forwards from the front sidewall of the housing in order to maintain a spaced interval from the rear surface of the drawer panel.
  • the interval support rib may be formed integrally with the housing. Therefore, a space may be formed between the drawer panel, which has a metal plate configuration, and the front sidewall of the housing, and the interval support rib may be located in this space, thereby increasing the volume of the drawer panel.
  • a downward rib extends forwards from the lower portion of the front sidewall of the housing in order to block a space formed between the rear surface of the drawer panel and the front sidewall of the housing.
  • the laundry treating apparatus further includes a control panel coupled with the top cover above the front sidewall of the housing in order to block a space formed between the front sidewall of the housing and the drawer panel above the front sidewall of the housing.
